WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 257,880, dated May 16, 1882.

Application filed March 20, 1882 To all whom it may concern:

Be it known that I, FRANK MCGLINTOOK, of West Union, Iowa, have invented a new and useful Improvement in Wind-Engines, of which the following is a specification.

My invention relates to that class of horizontal windengines having the sails attached to vertical sail-shafts which revolve in the same direction and with one-half the speed of the engine; and it consists in the manner of gearing the vane and sail-shafts together, so as to dispense with the use of chain-gearin g which has been used heretofore. I attain these objects by means ofthe mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of the engine, showingtw'o arms and sails; and Fig. 2, a top view or plan, showing the construction of the framework and the relative positions of the sails to each other and to the vane.

Similar letters refer to similar parts in both views.

The main shaft A, which revolves in journal-boxes bolted to the tower, (only the upper one, B, being shown,) has a casting, G,firmly keyed on its upper end, which forms the hub or center of the frame-work of the engine. The upper part of this casting is hollow, as shown in Fig. 1, in which the side is cutaway to show the interior. The arms D, E, F, and G (which I make of iron or other tubing) are attached to the sides of the box 0. At the outer extremity of each arm are cast-iron boxes H, having bearings above and below the plane of the frame in which revolve the sail-shafts I. Pieces of tubing L, L211", and L extend diagonally from box to box around the frame, and screw into the sides of the boxes H by right and left hand threads, so that they serve to thoroughly bind together and strengthen the frame-work. A piece of tubing, 0, is attached to the cover of the box (5, and firmly secured in a vertical position by stay-rods P, extending from the top of it diagonally downward to the arms. A shaft, M, with a vane, N, keyed to its upper end, passes through the tube 0, beingfitted to journal-boxes at the top and bottom. The sail-shafts I, with the attached sails, are fitted to revolve easily in the bearings' in the boxes H, and are geared to the (No model.)

vane-shaft M by means of bevel-gearing, which I prefer to construct as shown in the drawings. A bevel-gear wheel, a, is keyed on the lower end of the vane-shaft, inside of the box (),with its face upward. ()ther bevel-gear wheels, 1), matching the wheel a, and corresponding in number to the arms of the engine (two being shown in the drawings) gear into the wheel a, and are keyed or fastened with set-screws to horizontal shafts which extend outward through thehollow tubesor arms D, E, F, and G. ()n the outer end of each of these shafts is another bevel-gear wheel, fastened by setscrews or keys, and inside of the boxes H, and having the same number of teeth as the wheels I). These wheels gear into larger bevel-gear wheels, one of which is fastened by setscrews on each sail-shaft I. These large gear-wheels have the face turned in the opposite direction from the face of the center wheel, a, and have double the number of teeth. The box H on the right-hand arm in Fig. l is shown insection, so as to show the arrangement of the gear-wheels, 0 being the one on the outer end of the horizontal shaft running through the tube D, and at being the one on the sail-shaft.

The sails being set in the correct relative positions with the vane, as shown in Fig.2, the gear wheels' are all securely fastened, when the action of the wind on the sails will turn the engine. The vane-shaft M and center gear-wheel, a, will be prevented from turning,

however, by the force of the wind on the vane N, and the bevel-gearing will cause the sailshat'ts to revolve in the same direction as the engine with one-half the speed, and thuskeep the plane of the sails in the same relative positions with the vane.

The bevel-gear wheels may be of any conconvenient size; but the proportion as to num ber of teeth must be such that the sail-shafts make one revolution while the engine makes two revolutions.

The cap or cover to the central box, 0, and sheet-iron covers B. to the boxes H, together with the hollow arms D, E, F, and G, through which the shafts pass connecting the gearwheels I) and a, serve to protect the gearing entirely from the weather.

Having thus described my invention, what I claim as new, and desire to secure by Letters 'two revolutions of the engine cause the sail Patent is- 1.
